Answer:
Is the $4,000 savings per year sufficient to cover the anticipated college expenses?
Is Linda's 529 account underfunded?
What should be the annual deposit in Lynda's 529 account to cover entirely her tuition and fees?
What will be the PV of Lynda's college tuition on her 18th birthday?
Explanation:
Lynda's 529 account will have the following balance when she is 18:
future value = annual payment x annuity factor (FV annuity factor, 8%, 8 periods) = $4,000 x 10.637 = $42,548
her parents will make 4 withdrawals:
present value = annual withdrawal x annuity factor (PV annuity factor, 8%, 4 periods)
maximum annual withdrawal = $42,548 / 3.3121 = $12,846.23
required balance = $20,000 x 3.3121 = $66,242
annual payment = $66,242 / 10.637 = $6,227.51
